Arc Audio Nighthawk 400 x 2 / 800 x 1 Non-DSP Amplifier
When your system demands more power without added DSP complexity, the ARC Audio Nighthawk answers the call. Designed as the perfect companion to ARC Audio’s DSP-powered amplifiers like the Blackbird—and compatible with both current and future ARC DSP-equipped models—the Nighthawk delivers exceptional output, pristine sound quality, and installation flexibility, all in a matching chassis and industrial design for seamless system integration.
This fully bridgeable, high-end Class D two-channel amplifier produces up to 800 watts bridged at 4 ohms mono (CTA-2006 compliant), with low-distortion performance that rivals far more expensive reference amplifiers. Whether you're powering subwoofers, midbass drivers, or full-range components in high-efficiency or high-demand systems, the Nighthawk delivers headroom, clarity, and control—even under the most demanding conditions.
With balanced differential inputs, selectable stereo or mono configuration, and compatibility with ARC’s high-current speaker connection system, the Nighthawk is equally at home in motorcycles, marine builds, powersports environments, and audiophile-grade car audio systems alike.
ARC’s under-promise, over-deliver philosophy is in full effect. While rated at 800 watts bridged, real-world output comfortably exceeds specification—giving installers and competitors the confidence to push harder without compromise. Designed for real-world use, it delivers full-range performance from 10Hz to 32kHz, maintains thermal stability from -4°F to 180°F, and supports start-stop compliant voltage down to 4.6V.
Whether you're expanding an ARC DSP-based system or building a powerhouse standalone setup, the Nighthawk is built to elevate your sound—clean, powerful, and professional.
